Actually Steve, you're not 100% correct. I have seen (I was co-pilot) a bird strike take down a UH1-H from a damaged tail-rotor, not crashed but a forced landing due to serious vibration (precautionary) 40 miles out of Waco. In another case an A4D sucked a bird, broke a compressor blade and forced a shutdown. The compressor blades of a turbo-fan jet are finely balanced, and a bent or broken blade can cause a catastrophic failure. I do agree with you that a turbo-prop driven aircraft is unlikely to suffer from a prop strike, but the cockpit screen is another matter, besides giving the pilot a heart attack there is danger of debris entering the aircraft. Besides, if I was flying an aircraft at 1500' and was hit by a quad, that pilot, if identified, would be in line for some serious behavior modification thru pain association. You will have to admit there have been some very stupid postings on youtube, people doing some crazy things just for bragging rights. The guy who was bumping into buildings in NYC, the one who flew his quad over the runway here in CA, the guy chasing big horn sheep in a national park, and on and on. These kinds of boastful postings can only prove to the FAA that we are not responsible pilots, but just a bunch of unruly kid's, out for some fun regardless of the consequences, thus giving them a mandate for further restrictions. I also have never flown over 400' AGL, mainly because we have a high density of small craft in my area due to several General Aviation airfields close by, and the other is there is just not that much interesting to see from that height with the P3 camera.
